The Automatization Grade System Of Artisitic Skating Based On Client/Server

Client/Server ( C/S, Client/Servers) mode, rose in 1990s ,is a system structures of computer application. It has overcome the shortcoming of the traditional file server, has already become the main trend of development of the management information system, it not only offers a solution with high efficiency, low costs and easy to expand for information processing, but also accelerates the development of database technology as well.This paper introduces the Client/Server's structures, structure forming, the development of it. At this paper, recommend in detail the design and course of realizing of the "grade system of artistic Skating", a automated system base on Client/Sever.First of all, on the basis of systematically introducing the design principle. It introduces in detail the concrete design process of the system from two respects of design of network structure, the database server and system terminal software as well, at safe angle, systematic performances, system maintenance, the design of "grade system of artistic skating". This system adopts two layers of C/S structure. One Windows NT server and one set of datum processors set up the real time achievement database server, The server adopts Windows NT 4.0 as operating system, MS SQL 7.0 as database management system, through TCP/IP achieving visit the server. Visual Basic 6.0 was adopted to develop the terminal software, the system altogether includes affairs reminding subsystem, Sportsmen dividing into groups subsystem, referee giving a mark subsystem, achievement calculate subsystem and achievement issue subsystem, 6 subsystems. At the same time, the systematic security divide into server operating systems security, database management system security, client terminal software security, and network security as well. Because in C/S structure the factors influencing the system performance mainly include Client, network, Server, database and application system. It considers these factor fully from data distributing, database system setting up to raise systematic performance, it also consider the system maintenance from two respects, system running and database maintenance.Next, it introduces "grade system of artistic skating" some key technology that realize in detail from following several pieces of respect, As two database, MS Access and MS SQL Server, were mainly involved in "grade system of artistic skating". So hasrecommended the concrete implementation technique of visiting these two kinds of different databases in detail by VB. To local MS Access database of referee giving a mark, the visiting of the database is based on Microsoft Jet's database engine, Integrated Data control and DAO to realize. To access the SQL Server long-range database of sportsman's achievement is realized through RDO asynchronous technology. In achievement issue subsystem, involved a large amount of operation of text editing such as text display of the achievement, editing. In the program using RichTextBox realized the real-time control of the form of the characters, composing, etc.This system development filled in the blank of artistic skating achievements calculate, it offers reference for other sports achievements calculate system and it has practical meanings for realizing of sports achievements calculate modernization.
